Your boot-up result by just using the old drive as is, is normal. Too much has changed and the OS won't proceed with a proper boot-up.
I suggest, don't do the workarounds or the results maybe less than you want. It may work, but you've got one chance to do this and basically it becomes tiresome once it fails. You may not lose data but you could, that's the point, you're taking a chance. Google away, but in the time and effort you try the work arounds you can have your PC up and running, *CLEANLY* and install old data and pgms. in typical re-install. Image your old drive using another PC to do this and be safe with back-up. If you have another old drive clone to it if you like as yet another back-up method.
